Integrated Multi-Layered Fabric with Tunable Water Supply to the Photothermal Conversion Layer for an Efficient Solar Water Evaporation

Abstract

An efficient, low-cost, and easy-to-fabricate solar steam generator is needed to mitigate clean water scarcity in less-resourced areas. A balanced water supply demand (WSD) to the photothermal conversion layer (PCL) plays a key role in improved heat management and evaporation rate. Here, we designed a solar steam generator of integrated multi-layered fabric (IMLF) in which WSD can be tuned by varying the degree of polypyrrole (PPy) coating. The hydrophilic viscose yarn deposited with PPy is exploited as the surface, and the hydrophobic hollow polyester is used as the inner warp and weft yarn. Under 1 solar light intensity, IMLF attains an evaporation rate of 1.15 kg m–2 h–1 and a corresponding evaporation efficiency of ∼77.9%. Within 16 cycle tests, the evaporation rate of the IMLF fluctuates in the range of ∼1.00 to 1.16 kg m–2 h–1, indicating good cycle stability. Furthermore, the condensate obtained from actual seawater satisfies EPA and WHO drinking water standards. Our findings demonstrate that the IMLF is capable of effectively treating seawater and dyeing effluent.

Synergistic Effect of Hybrid CdSe Nanobelt/PbI2 Flake Heterojunction Toward Drastic Performance Flexible Photodetectors

“…In order to overcome the constraints of electronics relying on 2D PbI 2 material, mixed-dimensional heterostructures, as a possible solution for future multifunctional platforms, are assumed to be a convenient and effective approach. − Compared to the individual material, a mixed-dimensional heterostructure not only manifests the intrinsic properties of both individual components, as well as displays the extra desirable characteristics as a result of interplay at each component’s interface. − Low cost CdSe, as an important photoelectric chalcogenide of the II–VI group with a direct bandgap of ∼1.74 eV at room temperature, is widely explored in optoelectronics due to its excellent optical and electrical characteristics. − Among other morphologies of CdSe, a distinct 1D nanobelt like morphology with a rectangular shape at the edges has been widely studied in photodetectors. ,− Thus, the present study integrates the distinct properties of the aforementioned sensing materials to fabricate a well performing 1D/2D hybrid heterojunction photodetector. To date, there is no available approach for the fabrication of broadband flexible photodetectors utilizing a single crystalline CdSe nanobelt/2D PbI 2 flake hybrid heterojunction on a cost-effective flexible polyimide tape-based substrate.…”

Transfer Learning based Diagnosis and Analysis of Lung Sound Aberrations

“…Lung disorders are becoming the world's second leading cause of death. The acute and chronic respiratory conditions that directly impact individuals' health include COPD, asthma, lung inflammation, infectious diseases, tuberculosis, pulmonary embolism, sleep apnea, and occupational lung diseases [2,[14][15][16][17][18][19][20][21][22][23][24][25][26].…”
